"I used to ski in a place called Lech in Austria," Sir Cliff, 76, told Lorraine's Ross King back in 2017. "Charles and Diana used to come there, then they brought the children there. We'd always sing in the bar of the hotel. I saw Harry go [Sir Cliff imitates yawning], and we stopped and I said, 'Prince Harry, do you know any rock n roll?' He said, 'Well yeah, do you know Great Balls of Fire?' 'Great Balls of Fire', I said, 'Yeah I do, but how do you know it?' [He said], 'Oh mummy plays it all the time'."

"You will never know what I went through," he said. "We want to try and get something changed, so therefore something new has come into my life that has nothing to do with music but has something to do with lifestyles and the injustices that can take place in our society."
The singer was cleared of historic child abuse claims last year
Sir Cliff was subjected to a 22-month police investigation regarding historic child abuse claims, that was mired in controversy from the start. In June 2016 Sir Cliff was cleared of historic child abuse claims. The Crown Prosecution Service announced that it has "carefully reviewed" the case and decided that there was "insufficient evidence to prosecute".
In a statement, Sir Cliff said he was "obviously thrilled that the vile accusation and the resulting investigation have finally been brought to a close". He added: "I have always maintained my innocence, cooperated fully with the investigation, and cannot understand why it has taken so long to get to this point."
